Abstract
The growth, yield and quality of tomato largely depend on soil and climatic
conditions and also on variety. Among these, proper application of plant growth
regulators and Zn plays a vital role. The field experiment was conducted at Sher-eBangla
Agricultural University Farm, Dhaka, Bangladesh during October 2017 to
April 2018 to evaluate the effect of foliar application of IBA, GA
and Zn on yield
and quality of tomato. Single variety BARI Tomato-14, and foliar application of IBA
5ppm, GA

5ppm and Zn were used to conduct this experiment. The experiment was
laid out in a Randomized Complete Block Design (RCBD) having single factor and
replicated three times. Data were collected on plant height, number of leaves plant
,
number of branches plant
-1
, Leaf Area Index(LAI), chlorophyll content of leaf,
number flowers cluster pant
-1
, number of fruit plant
-1
, weight of fruit, yield hectare
,
Vitamin-C content and TSS% content. A statistically significant variation was
recorded in terms of all the characters related to growth and yield quality of tomato.
The maximum plant height, number of branches plant
